COMBINED LETTER-SHEET AND ENVELOPE.

SPECIFICATION forming part' of Letters Patent No?. 287,555, dated October 30,

Application filed July 17,1883. (no model.)

To all whom t may concern: f

Be it known that I, BERNHARD LoEWEN- EACH, of Milwaukee, in the county of Milwaukee, and in the State of Wisconsin, `have invented certain new and useful Improvements in Combined Letter-Sheet and Envelope; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to envelopes and letter-sheets combined together in one piece; andy mailing or delivery. Fig. 8 isa view of thev form of my device known as the note style,77 open; and Fig. 4 is an enlarged view of the same folded and closed.

A is the letter-sheet, and B is the envelopesection, the latter consisting ofthe central or address portion, b, `and the wings b b, which extend on each side of the central portion just as far as the side edges of the letter-sheet A, but no farther, and are solid therewith, save that a line of minute perforations, a, extends between the wings b of the' envelope-section and the wings or side portions, a', of the letter-sheet A, from each side of the central portion of the said envelope-section outward, as shown. The object of this is to keep the envelope and letter integral during printing, (when it is desired to put letter headings upon them, as shown at yC i-n full lines and C in dotted lines,) and yet have the parts A and B separable at these points when the letter has been written-and -is ready for folding,-

preliminary to mailing or delivery.

Of course it will be understood that my let-` ter-sheet (and note-sheet) may be either ruled, asshown, or perfectly plain, and that the sheet may or may not have a printed card or letterhead on it, as preferred. W'hen such card is printed, it is upon the reverse side fronrsimilar printing on the envelope-section, as indicated by the dotted lines at C on the latter. As stated, I nd the perforations a most convenient when the sheet is to be ruled or printed; but, if desired, the parts A and B may be sepained only bycutting the envelope.

rated at their sides by a' simple cut instead, or' l by indentations instead of perforations.

Above the central portion, b, of the envelope- 5 5 section B, I form the sealing-flap b2, and vthis is provided with a line of mucilage, lfas is one of the envelope-wings b'. The note style of combined letter-sheet and envelope, Figs. 3 and 4, is constructed in exactlyY the same way as the just-described letter style, except that the envelope-section joins the letter-sheet f Y preferably at one side rather than' at the top.

To indicate the manner'in which the articles are to be folded, I have shown dotted vor broken lines, (composed of alternate dots and dashes 5) and it will readily be understood that, rst, the.lettersheet is doubled upon itself, so that all the lines of writing will b e inside, and then, at the perforations or indentations a a, the wings ofthe letter-sheet-are separated fromthe wings ofthe envelope-section, and the doubled letter-sheet wings are folded in over each other from right and left, and then all thisthrice-doubled letter-sheet portion is again brought up, covering the inside of the central or address portion, Z1, of the envelope-section B, and the wings b b folded over that, the last wing having its line-of gum b3 moistened to secure it upon the other or rst-foldedwing, b; and, lastly, the sealingflap b2 is brought down over and on top of the 'win gs b, and its line of gum b3 is also moistened,

thus securing the whole compactly and thor- 1 oughly and permitting. the letter to be exam- For an additional safeguard against tampering with th-e sealed letter, the line ofV gum may be extended along the edges of the wings b of the envelope-section, as shown atb4 b4 in Fig. l, just above the rows of perforations or indentations a aj but this is optional and hardly necessary, as the sheet will be well secured within its envelope-section without this precaution.

The note style is folded and secured in kprecisely the same way.

My combined letter-sheet and envelope can Y .also loe used for printed circulars, and in such case the flap b2 can be left ungummed, so that the said circulars may be in condition for the inspection of postmasters, who can thereby ascertain that theyV contain no written matter without unfolding the same, it being only necessary, with the printed circulars, to fold the IOU printed sheet iirst in just the reverse Way to that described for the Written sheet, so 'as to expose rather than conceal the contents.

The form of device denominated the note style is particularly adapted for such printed circulars, leaving the ilap b2 ungummed, as stated; or the flap b2 might be omitted for such circulars, if desired.

Having thus described my inventio11,\vhat I claim as new, and desire to secure byLetters Patent, is-

l. A combined letter-sheet and envelope composed of the parts A and B, forming the lettersheet and independent envelope, respectively, and the Wings a and b of the said parts, hav,- ing their outer edges in line with each other, Without any projecting' portions, and adapted to be separated by means of perforations, &c., when the device is to be folded, substantially as set forth.

2. In a combined letter-sheet and envelope, the part A, having wings a a', in combination with the part B, having wings b b', one of which is provided With a line of gum, b, the Wings a and b being made separable by the rows of perforations, cuts, or indentations a a, and the sealing-ap b, having also a line of gum, b, substantially as set forth.

3. In a combined letter-sheet and envelope, the combination of the part A, with wings a a, forming the letter-sheet, the part B, with wings b b', constituting the envelope-section, the wings a and b having perforations, cuts, or indentations between them, and the sealingflap b2, the said flap and Wings of the envelopesection being provided with the lines of gum b3 b3 b* 0*, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand, on this 2d day of July, 1883, in the presence of two Witnesses.
